Hi, @Anthony and welcome to FUD! If you get a chance, please feel free to drop by and introduce yourself!
To your question, It is my understanding that although the 3 has better OS, Battery life, display among other things, if you don’t need LTE connectivity or a GPS for fitness tracking, there really isn’t anything added by the 3 that you don’t already have in the 1 or the 2 series.
Nice to have you here and looking forward to interacting more with you in the future!
